Haptic Interfaces for Individuals with Visual Impairments Issue 07 – 2018 Journal –Peer Reviewed BENJAMIN VERCELLONE Missouri Department of Social Services Haptic Interfaces [email protected] JOHN SHELESTAK for Individuals with Department of Biological Sciences, Kent State University [email protected] Visual Impairments YASER DHAHER Department of Mathematics, Kent State University [email protected] & ROBERT CLEMENTS Department of Biological Sciences, Kent State University ABSTRACT [email protected] Vision enables a person to simultaneously perceive all parts of an object in its totality, relationships to other objects for scene navigation, identifcation and planning. These types of perceptual processes are especially important for com- prehending scenes in gaming environments and virtual representations. While individuals with visual impairments may have reduced abilities to visualize objects using conventional sight, an increasing body of evidence indicates that compensatory neural mechanisms exist whereby tactile stimulation and addi- tional senses can activate visual pathways to generate accurate representations. The current thrust to develop and deploy virtual and augmented reality systems capable of transporting users to diferent worlds has been associated with a push to include additional senses for even greater immersion. Clearly, the inclu- sion of these additional modalities will provide a method for individuals with visual impairments to enjoy and interact with the virtual worlds and content in general. Importantly, adoption and development of these methods will have a dramatic impact on inclusion in gaming and learning environments, and especially in relation to science, technology, engineering, and mathematical (STEM) education. While the development, standardization and implementa- tion of these systems is still in the very early stages, gaming devices and open source tools are continuing to emerge that will accelerate the adoption and integration of the novel modes of computer interaction and provide new ways for individuals (with visual impairments) to experience digital content. Here we present the rationale and benefts for using this type of multimodal interac- tion for individuals with visual impairments as well as the current state of the art in haptic interfaces for gaming, education and the relationships to enhanced end user immersion and learning outcomes. As these technologies and devices are adopted and evolve, they are poised to have a dramatic impact on entertain- ment, education and quality of life of individuals with visual impairments.

As such, the realm of gaming has been heavily focused on increasing rendering quality to provide greater acuity and immersion for the user. This has undoubtedly pushed both the hardware and sofware forward, however, little of this development efort has been focused on how to convey in game elements without the use of vision, specifcally for gamers who are visually impaired. Touch based methods have been classically used by the blind as a substitution for vision, with the most obvious example being the braille method of tactile writing whereby a system of raised bumps organized into six block cells, typically on embossed paper, are used to represent characters and punctuation. Invented by Louis Braille (Duxbury Systems, 2017) in the early 19th century this method has stood the test of time afrming the utility of touch, or haptic, sensations as an alternate method to convey visual concepts to the blind. In the realm of computer in- teraction for gaming and visualization of complex imagery, haptics have been integrated for many years via “rumble pads” and force-feedback devices provid- ing users the ability to crudely physically sense digital events (Orozco, 2012). While these systems ofer a level of multi-modal interaction for the sighted user, they have had limited use for seeing impaired individuals with most games for the visually impaired based around the use of sound for cue identi- fcation. However, tactile games for individuals with visual impairments based of popular WII console games (VI-bowling and VI-tennis) have been successfully developed using vibration to indicate ball timing, controller position and object placement (Tony, 2010). The crudeness of these cues and the difculty in iso- lating them spatially limits the vibration only approach. It does afrm the prin- cipal and ability of using tactile feedback to accurately represent spatial concepts within the gaming realm. This would be especially true for haptic interfaces referenced to real world space with rapid refresh-rates that could provide much of the information that a sighted gamer would get visually. While individuals with visual impairments may have reduced abilities to vis- ualize objects using conventional sight, an increasing body of evidence indicates that compensatory mechanisms exist whereby tactile stimulation and additional senses can activate the visual system to generate accurate spatial representa- tions. Indeed, reading braille is known to activate the visual cortex (Burton, 2006) of the brain in the blind (a region that typically codes visual informa- tion) and refects the recoding of tactile sensations into “visual” signals. Studies also indicate that blind participants are typically able to better discriminate 3D shapes via tactile and haptic interaction (Norman, 2011) than sighted persons. Research evidence indicates the blind have diferent patterns of activation in the brain during haptic tasks (Roder, 2007) as well as during vibrotactile stimula- tion (Burton, 2004). Moreover, large-scale changes manifested in both struc- tural and functional diferences in brain connectivity indicate that the changes are not limited to the visual areas of the brain but refect large changes in associ- ated areas and “visual” perception as a whole. The idea of perceptual learning and substitution of sensory signals (where visual input is substituted for touch) can aford the ability of “sight” to subjects who are physically incapable of do- ing so. The remarkable capacity of the human brain to reorganize itself results in long lasting changes. This type of reorganization of visual pathways afrms the utility of a haptic approach to represent virtual environments to individu- als with visual impairments. This will not only provide a means for additional brain reorganization but also that inherent diferences in their brain structure suggests that perceptual learning will be more benefcial in this population with a dramatic impact on in game orientation and perception. With the advent of new devices facilitating the generation of complex spatial and temporal representations of real world and virtual scenes, as well as the incorporation of tactile devices that allow physical interaction with computer generated imagery has emerged a novel platform for augmenting seeing im- paired interfaces. Coupling this with evidence that individuals with visual im- pairments are able to acquire spatial knowledge using ancillary neural pathways via harnessing additional senses indicates that this is a promising and potentially game changing avenue to enhance user engagement and immersion. Here we detail the current state of haptic technologies as it relates to using these meth- ods for encoding spatial information to individuals with visual impairments for both gaming and education. We begin with a discussion of the available hard- ware, and then we propose how these technologies could be used to convey in game information and learning as well as identify barriers and potential solu- tions. Finally, we address future developments and next steps for dealing with these innovations in the long term. NEW TECHNOLOGIES AT STAKE HAPTIC MEDIA Simple haptic feedback has been a part of gaming now for many years, but newer technologies are allowing for a larger range of haptic sensations across diferent digital experiences. Newer controllers, such as the Steam controller have improved on this feedback, allowing for a greater range of in-game infor- mation through fner control of the haptic output including haptic informa- tion on speed, boundaries, textures, and in-game actions (Steam Store, 2015). Microsof is developing various haptic controllers to achieve various sensations such as texture, shear, variable stifness, as well as touch and grasp, to enhance the level and variety of stimulation provided by a VR experience (Strasnick, 2018; Whitmire, 2018). Haptic styluses ofer a diferent handheld experience via force feedback instead of vibrotactile feedback and can be used to interact with objects, or as a physical interface for more advanced simulations (Stein- Issue 07 – 2018 Haptic Interfaces for Individuals with Visual Impairments berg, 2007). Further, advances in wearable haptics; gloves, vests and full body suits have also expanded the potential experience of video games. Gloves allow for diferent actuators to be woven into the fabric or attached as an exoskeleton to achieve both vibro-tactile and force feedback (Virtual Motion Labs, 2018; VRGluv, 2017). The force feedback from the exoskeleton can defne

In this paper, we argue and present evidence from vast research that VR is an excellent tool in engineering education. Through our review, we deduced that VR has positive cognitive and pedagogical benefits in engineering education, which ultimately improves the students’ understanding of the subjects, performance and grades, and education experience. In addition, the benefits extend to the university/institution in terms of reduced liability, infrastructure, and cost through the use of VR as a replacement to physical laboratories. There are added benefits of equal educational experience for the students with special needs as well as distance learning students who have no access to physical labs. Furthermore, recent reviews identified that VR applications for education currently lack learning theories and objectives integration in their design.

  • Design Architecture in Virtual Reality
    Design Architecture in Virtual Reality by Anisha Sankar A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Architecture Waterloo, Ontario, Canada, 2019 © Anisha Sankar 2019 Author’s Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. - iii - Abstract Architectural representation has newly been introduced to Virtual Real- ity (VR) technology, which provides architects with a medium to show- case unbuilt designs as immersive experiences. Designers can use specialized VR headsets and equipment to provide a client or member of their design team with the illusion of being within the digital space they are presented on screen. This mode of representation is unprec- edented to the architectural field, as VR is able to create the sensation of being encompassed in an environment at full scale, potentially elic- iting a visceral response from users, similar to the response physical architecture produces. While this premise makes the technology highly applicable towards the architectural practice, it might not be the most practical medium to communicate design intent. Since VR’s conception, the primary software to facilitate VR content creation has been geared towards programmers rather than architects. The practicality of inte- grating virtual reality within a traditional architectural design workflow is often overlooked in the discussion surrounding the use of VR to rep- resent design projects. This thesis aims to investigate the practicality of VR as part of a de- sign methodology, through the assessment of efficacy and efficiency, while studying the integration of VR into the architectural workflow.

  • Self Representation and Interaction in Immersive Virtual Reality
    Self Representation and Interaction in Immersive Virtual Reality Eros Viola a, Fabio Solari b and Manuela Chessa c Dept. of Informatics, Bioengineering, Robotics, and Systems Engineering, University of Genoa, Italy Keywords: Virtual Reality, Self Representation, Intel Realsense D435, Interaction, Leap Motion, Manus Prime Haptic Gloves, Alignment, Rigid Transformation, Live Correction. Abstract: Inserting a self-representation in Virtual Reality is an open problem with several implications for both the sense of presence and interaction in virtual environments. To cope the problem with low cost devices, we de- vise a framework to align the measurements of different acquisition devices used while wearing a tracked VR head-mounted display (HMD). Specifically, we use the skeletal tracking features of an RGB-D sensor (Intel Realsense d435) to build the user’s avatar, and compare different interaction technologies: a Leap Motion, the Manus Prime haptic gloves, and the Oculus Controllers. The effectiveness of the proposed systems is assessed through an experimental session, where an assembly task is proposed with the three different interaction medi- ums, with and without the self-representation. Users reported their feeling by answering the User Experience and Igroup Presence Questionnaires, and we analyze the total time to completion and the error rate. 1 INTRODUCTION The focus is to develop a framework that is compat- ible with the most common head-mounted displays In current Virtual Reality (VR) applications, the vi- (HMDs), and that can also be extended to other track- sual feedback of the user’s body is often missing, de- ing devices, both for the body tracking and for the spite the abundance of enabling technologies, which hands and fingers tracking.

The idea of modern VR can be traced back decades, but because of the limitations of the technology (both hardware and software), we are only now exploring its potential. At present, VR can be used for tele-surgery, PTSD therapy, social training, professional meetings, conferences, and much more. It is no longer just an expensive gimmick to go on a momentary field trip; it is a tool, and as with the automobile, personal computer, and smartphone, it will only evolve as more and more adopt and utilize it in various ways. It can provide a three dimensional interface where only two dimensions were previously possible. It can allow us to express ourselves to one another in new ways regardless of the distance between individuals.

Venn Marquette University, 2018 Virtual reality (VR) can stimulate active learning, critical thinking, decision making and improved performance. It requires a medium to show virtual content, which is called a virtual environment (VE). The MARquette Visualization Lab (MARVL) is an example of a VE. Robust processes and workflows that allow for the creation of content for use within MARVL further increases the userbase for this valuable resource. A workflow was created to display biomedical computational fluid dynamics (CFD) and complementary data in a wide range of VE’s. This allows a researcher to study the simulation in its natural three-dimensional (3D) morphology. In addition, it is an exciting way to extract more information from CFD results by taking advantage of improved depth cues, a larger display canvas, custom interactivity, and an immersive approach that surrounds the researcher. The CFD to VR workflow was designed to be basic enough for a novice user.
